"title": "Inspiring",
"body": "I am a Pianist and I have been using Hanon exercises on and off for many years to improve my technique. However as with other mechanical exercises, they can be quite draining because they are repetitive and unmusical. Now with Harmony Cloud Pro, I now have a means to complete Hanon (and other methods). HCP has inspired me to truly engage in deep practice as I can now simultaneously work on my ears and my technique. The only limit to what you can achieve with this app is your own imagination. MC.",

{
"rating": 5,
"title": "Improve your musicianship",
"body": "I recommend this app to any musician looking to deepen their sense of harmony. I also recommend to really put in some time with the challenges / chord collections / practice techniques / etc. It takes a bit to start appreciating (and hearing) what’s going on under the hood. This is not an app with random chords thrown at you, but a very thoughtful approach on how to build a contextual and musical ear as you expand out the sonorities.",

"title": "Amazing App",
"body": "This is a wonderful resource for both students and educators. It’s clear that a lot of love and hard work went into creating it, thanks to one of the great musical minds of our generation, Stefon Harris. I’ll be using this in my own studies, as well as incorporating the introductory functions as an ear-training tool for my students.",
